Telephone operation

Basic phone operation

During an outside call:
1. Press and release 

[HOLD] to maintain the 

connection to the call on the active line.

2. Press and release the 

LINE button of another 

line to make or answer another call.

3. To return to the first call, press

 [HOLD] to put 

the current call on hold. Then press the

button of the original line.

To ensure call privacy, this phone allows only one 
set at a time to use a line.

During the call, press the 

[LINE] button for the 

call. You’ll hear a short beep. Others can now join 
the call by pressing the appropriate line button.

Press the 

[LINE] button again during the call. 

You’ll hear a double-beep. The other phones will 
be dropped from the call.

Call privacy is automatically restored when 

you 

end the call.

  When a non-system phone answers a call, 

any other system phone can pick up the call 
by pressing the 

[LINE] button. Once a system 

phone picks up the call, call privacy is activated 
and no other system phones can listen to the 
call unless call privacy is canceled, but non-sys-
tem phones which share that line can still join 
the call.
